For the last few years I’ve been adding chapters to my TV shows demarking the transition between the programming and commercials.
Plex has detected these chapters and it has allowed me to quickly skip over the commercials while watching the TV shows.
Sometime in the March time-frame, new files that I’ve added don’t have the chapters detected. Plex was displaying them as if they didn’t have chapter information. For the first month I thought it was something that I was doing wrong, so I went back and looked at Comskip and ffmpeg to see what had broken. To my surprise I saw that the chapters were still there, both ffprobe -show_chapters and VLC easily detected the presence of the chapters. It is only Plex that can’t seem to find them.
What has changed to break this, is this a new bug? I have video files that show this effect, but they are fairly large.
I saw the issue with chapter thumbnails, but I thought that was different because I have chapter thumbnail creation turned off. I just need Plex to detect that there are chapters so I can move between them, not to create thumbnails for them.
From what @trumpy82 said it seems like Plex is still capable of detecting chapters, it is just that the maintenance task that would scan them and detect them isn’t working correctly. Is that accurate?
Sounds like they may be tied together in some way which may interest the dev team.
Plex is having an issue in the existence of chapters and to create thumbnails.
The above setting makes no difference.
So one might think the reason why thumbnails are not created is because Plex doesn’t see the existence of the chapters.
I’m currently having to run analyze on any videos added for chapters to show up. Then manually run the Plex Scanner to generate the chapter thumbnails.
